This invention relates to Ventilating apparatus, and more particularly to Ventilating apparatus of the type suitable for installation in a window opening and which operates to admit and/or exhaust air from a room.

Apparatus of this type heretofore known to me,

usually comprises a Ventilating unit comprising.

a.n casing xedly mounted on the window sill and having inlet and outlet openings therein conm necting the room space with the outside atmosphere. Air moving mechanism is usually mounted within the casing and operates to move the air therethrough. The lower sash rail of the Window has' a sealing engagement with the cas.-

ing; and the spaces at each end of the casing,

defined bythe end of the casing, the adjacent window jamb, the lower sash rail of the window and the window sill, are usually closed by filler blocks having sealing engagement with the ele- 2'0 ments named and serving to prevent the passage of air between the outside and room space except through the casing.

An object of my invention is to provide a filler block of the above character which is of improved iorm, is simple and inexpensive to construct and install, and one which is pleasing in appearance.

The invention consists in the novel construction andcombination of parts, to be more fully described hereinafter, and the novelty of which o will be particularly pointed out and distinctly claimed. f,

Intheaccompanying drawing, to be taken as a part of this speciication, I have fully and clearly illustrated a preferred embodiment of my invention, in which drawing- Fig. 1 is a front elevation, showing my improvement as installed in a window opening;

Fig. 2 is an enlargediragmentary view partially in plan andl partially in horizontal section, the

View being taken on the line 2 2 of Fig. l;

taken on the line v Fig. 3 is a vertical section t-t of Fig. 1; v

Fig. 4 is a perspective view showing my improved form orf/filler block with one end member removed; and' Fig. 5 is atdetail elevatlonai view of the inner face of an end member. Y

Referring now in detail to the construction illustrated, the reference numeral lll indicates a window sill, the numeral Il a pair of spaced window jambs, and the numeral l2 the lower or sill rail of va window sash I3 slidably mounted in the jamba A window ventilator It is centrally mounted in the partially opened window and rests onthe window sill i0 and has a sealing en- Cll. 98-949 gagement with the lower sash rail l2 of the window. insofar as the present invention is' concerned, the ventilator it may be of any suitable construction. The one here shown comprises a casing it secured to the window sill by suitable screws it and provided at its front with outlet openings il, through which air flows into the room. The openings Ill are controlled by adjustable louvers i8 which'operate to direct the air to dilerent desired portions of the room or to close the outlet openings. The inlet opening for the air is located at the rear of the casing and xed louvers i9 are mounted over the inlet openv ing to prevent the entrance of `rain or snow into the ventilator. Suitable mechanism (not shown) may be mounted in the ventilator for admitting fresh outside air into the casing and forcing such air into the room through the louver-controlled outlet openings Ill.

The spaces between the ends of the casing ,i5 and the Window jamb l l are closed by filler blocks til, there being one filler block for each space. The iiller blocks are rectangular in shape and iit within vertical guide channels 2i and 22 secured to the ends of the ventilator and the window jambs, respectively. The upper face of each of the filler blocks is provided with a suitable strip of felt it, or similar material, for eiecting a sealing engagement between the lower sash rail i2 and the block 2t. yThe lower part of the ller block 2li ts tightly against the outside face it of the window sill it and thereby prevents the passage of air by the block at this point.

In accordance with the present invention, the

filler block comprises a top member 25, a bottom member 2t, end members 2l and a panel member 23. The top and bottom members 2t and 2t extend between the end of the ventilator and the windowjamb and are provided on their opposed or inner iaces with longitudinally extending grooves 3ll. The end members 2l are also provided with longitudinally extending grooves 3i on their inner faces which. when in assembled position, grooves 30 to provide a continuous groove lying` in a single plane. The top and bottom members and the end members form a hollow rectangular frameV fitting the space at an end of the ventilator, and the panel member 2t is securely heldin the frame by its outer edges tting in the grooves Sil and 3i. v

The end members 2l are provided at each end thereof with tongues 32 which slidably t in the grooves 3t of the top and bottom'members. The` front and rear inside Vcorners of the top and communicate with the bottom members are beveled as indicated at 3l and the end members are provided at their ends with notches 34 having beveled inside surfaces 35 which engage the beveled surfaces of the top 5 and bottom members and thereby provide smooth joining surfaces between the end members and the top and bottom members. are also suitably beveled at their front and rear inside corners, as indicated at 36, so as to provide with the bevel 33 a continuous bevel to the inside corners of the frame and thereby addto the pleasing appearance ofthe block 20.

The top member 25 is provided with an upwardly extending ange 31 which extends for the full length thereof and is rmly secured thereto. The outer face of the flange 31 lies in the same plane as the front face of the top member 25. The upwardly extendingflange member 31, when in position, lies at the inside of the lower sash rail I2 and provides a weatherproof joint therewith.

By reason of the construction just described, a

iiller block is provided which requires no com-l plex tting when installed, such as mitering the frame members, or cutting, iitting and applying molding. -The filler block is pleasing in appearance and can be made and installed quickly and simply and at a low cost. 1

This improved filler block construction is admirably suited for the installation of ventilators in windows of varying widths. The ventilators, of course, are of standard dimensions and the distance between the sill and the lower sash rail will therefore remain the same for all windows. Hence, the length of the end members 21 and the height of the panel 28 can be made standard-to bridge this distance. The length of the top and bottom members and the panel 28 will vary with the particular width of window and these parts can be easily cut at the time of installation.

'I'he filler blocks may be made up for standard heights and for a series of standard lengths. For each installation, filler blocks may be supplied which have the standard length dimension which is greater than and nearest to the length 45 requirement of the spaces, and the blocks cut at the time of installation. Preparatory to installing, the blocks Vare first disassembled by simply sliding one of the end members out of the grooves 30 and then withdrawing the panel member 28 from the grooves. 'I'he top and bottom members 25 and 26 and the panel 28 may then be readily cut to fit the particular dimension between the end of the ventilator and the window jamb. After cutting, the panel may be readily inserted in the grooves and the previously removed end member 21 replaced.

An alternative manner of preparing the ller block for installation is indicated in Fig. 4. 'I'he panel 28 of theiiller block has been, previously cut to the required dimension and reinserted in the frame. The disassembled end member 21 is then readily slid into place, leaving overhanging portions of the top and bottom members. The overhanging portions may then be cut and the ller block placed in the channels 2| and 22.

Insofar as certain ofthe aspects of the invention are concerned, the ller block may be formed of any suitable material. In the particular em- 70 bodiment of my invention which is shown on the accompanying drawing, the top, bottom and end members arev formed of wood which may be lsimply and easily grooved and notched in the manner shown. The panel member 28 maybe 75 either formed of ply-wood or of glass. In the The end members commercial product, it is the intention that the filler blocks be furnished 'to thecustomer with ply-wood panels, who may substitute glass panels if desired. However, this practice may vary. The upwardly extending `flange 31 may be suitably formed of ply-wood, which gives a very strong and sturdy flange that cannot be easily broken.

What.I claim and desire to secure by Lette Patent of the United States isz- 1. A filler block for closing the space defined by a window jamb, one end of a ventilator, a lower rail of a window sash, and a window sill; comprising top and bottom members extending between the window jamb and the ventilator at the upper and lower sides of said space, respectively; end members arranged adjacent the window jamb and ventilator', respectively, and connecting the ends of the` top and bottom members and forming therewith a substantially rectangular frame bounding said space; the top and bottom members and the end members being each provided with a groove in the inside face thereof and extending for the full length thereof andv each groove connecting at its opposite ends with adjacent grooves toprovideone continuousgroovelying in the same plane; at least one of said end members being provided at its opposite ends with tongues slidably fitting in the ends of the grooves of the top and bottom member, respectively and a panel of the same shape as the inside of the frame detachably mounted in the frame with its edges slidably received by said grooves.
